Did you wire the network cable to your router? Don’t wire it to your laptop directly. Your laptop must run in same LAN network with the gateway. So you can use the tool to discover the gateway. ---

I also having the issue with discovering the gateway. I’ve updated gw to “firmwareVer”: “1.2.5.6” and now config tool does not work for me on android and windows 7 x64. Do you have maybe description of configuration API or new version of config tool. Gate way is sending the request, so it works and endpoint show me device information { “firmwareVer”: “1.2.5.6”, “hardwareVer”: “4.0”, “mac”: “CC:50:E3:85:A1:B4”, “sn”: 8757684, “validate”: 1 } Thank you. ---

Hi, The config tool discover gateways by the API you post. e.g. - Let’s say your gateway’s IP is 192.168.1.123 - config tool request [http://192.168.1.123/](http://192.168.1.123/) , It will show the list if the app request the API successful Please confirm your android work in same LAN network and you type right LAN IP in the app ---

HI, yes it is in the same LAN. I’ve tried on different android version but without success. Before update it is worked well. Thank you. ---

did you type right IP in the config tool? - Let’s say your gateway’s IP is 192.168.1.123 - You should type 192.168.1.1 in the config tool and tap on “Discover” - The config tool start scan 192.168.1.1 ~ 192.168.1.255 for find devices ---

Hi, I’m also having the same issue, how can I type the IP in the config too? is the config tool you mention is for PC Version v.1.2.2, I was connecting through ethernet and the issue is my router couldn’t find the device. Any suggestion on how to solve this? ---

Please open a new topic for your issue. Some questions - Do you use the power cable we shipped? - What’s about the power adapter? Is it 5V/2A? - Firmware version? ---

Thank you, The issue is with the Power Adapter we use recommended 5V/2A. now the device is detected. Other issue is the Ethernet MAC address indicated outside the package is for the Bluetooth? because from my network detection the Ethernet MAC address are completely different. ---
